I’ve been helping friends begin growing and many are confused about light. Some think they can get away with fewer hours of light if they use stronger bulbs or are in areas with stronger sun. As you likely know, the plant runs according to the sun and the sun is very consistent. The plant likes consistency.
I guess this would be why that is. In this article they discuss how plants use math (calculus) to figure out to ration energy based on expected hours of darkness.
Pretty amazing and not surprising. I just sexed and rooted a cutting at the same time so it doesn’t surprise me that they can do math better than me too
